So3 Lewis Acid Or Base. I think it is acid, because there is a question that asks the acid site of so3. It can act as a lewis acid because the central sulfur can accept a lone pair, however not in the form of a bond to hydrogen.

Sulfur trioxide is a potent sulfonating agent, i.e. However, it can accept two. Since the sulfur atom in so 3 is electron deficient, so 3 (sulfur trioxide) is a lewis acid. In bh 3, boron has only six valence electrons. Web a lewis base is defined as any species that can donate a pair of electrons, and a lewis acid is any species that can accept a pair of electrons. Thus (ch 3) 2 s donates an electron pair on sulfur to the boron atom of bh 3. It can act as a lewis acid because the central sulfur can accept a lone pair, however not in the form of a bond to hydrogen. Lewis base is any base which is an electron pair donor. Return to “lewis acids & bases”. A lewis acid is an electron pair acceptor.
His theory gave a generalized explanation of acids and bases based on structure and bonding. Return to “lewis acids & bases”. Like oxygen, the sulfur atom in (ch 3) 2 s has two lone pairs. Since the sulfur atom in so 3 is electron deficient, so 3 (sulfur trioxide) is a lewis acid. Web by psiberg team last updated: So 3 is a strong lewis acid readily forming adducts with lewis bases. Hence, s so 3 is an acid. It is therefore electron deficient and can accept a lone pair. A substance that can accept an electron. The result is the formation of a coordinate covalent bond and the compound formed is called an adduct. Web lewis acid is any acid which is an electron pair acceptor.
